Application filed March 1l, 1911.

To all whom t may concern:

Be it known that l, ltlnmmn' lfl. Boven, a citizen ci' the United States, residing at lensacola, in the county ot Escambia and State of Florida, have invented certain new and useful improvements in rlurpentine- Cups; and ll do hereby declare the following to be a full, clear, and exact description et the invention, such will enable others skilled in the art to which it appertains to make and use the saine.

rlhis invention relates to improvements in devices tor collecting sap troni trees, and is particularly designed as a cup `lfor gathering turpentine.

The chipping and cupping ot a tree, hereutotore practiced, tends to stop its growth,

weaken the tree, and kill the timber, leaving the tree open to the ravages ot lire and the other elements. By the present system the tree is not weakened to any susceptible dcgree, and the hole that is bored will heal up in two or three years time, leaving scarcely a scar, so that the tree can be worked tor turpentine purposes indefinitely. Also, in many instances, considerable loss is en- `ailed owing to a portion oi' the turpentine flowing from the cut, down trunk ot the tree, without being conveyed int-o the cup.

rllhe primary object of the present invention is to overcome these objections and to more eirlectively entractthe turpentine, with substantially no loss ot' the tluid.

lWith this primary object in view the invention broadly consists in providing a cup having a conduit leading to the interior thereogt, the other end being snugly fitted in a bore made in the tree, a piston being located within said cup, the piston and cup being operative relatively to each other to tend to create a vacuum in the cup on that side et the piston opposite to the entry ot the conduit into the cup.

lt will be understood that the invention is not restricted to the enact details shown and described, but t'or the purpose ot disclosure reference is had to the accompanying drawings illustrating practical embodiments of the same, in which drawings like characters designate the same parts in the several views, and in which- Figure l is a view showing my invention applied to a tree, the cup and piston and operating nut being shown in longitudinal section. llig. 2 is a view substantially similar to Fig. 1, showing a modified torni in Specification of Letters Patent.

which the piston is movable and the cup stationary.

Referring to Fig. l, l designates a tree suitably bored, as at Q, preferably at an angle et substantially 45o and et a depth corresponding to a depth which will be most satisfactorily permitted by the size of the tree.

3 designates a conduit consisting et a pipe which may be threaded at its end Ll; tor the more effectively securing the pipe within the bore, the lower end oit the `pipe being bent preleably at an angle of 45 to depend substantially parallel with the t-ree or vertically of the ground. At the lower end oit the pipe is secured a piston head of any suitable construction, but provided with a peripheral edge that will frictionally en gage the interior wall ot the cup, to be rel'erred to, in such manner as to etlectively prevent leakage therearound. ln Fig. l this piston head is shown as consisting of the metallic or other stitl'l disks 5, between which is interposed a washer or gasket (S of rubber, leather, or similar flexible material,

the peripheral edge et which snugly engages y the inner wall of the cup 7 termed oi any suitable material, the bottom of the cup be: ing closed, as at 8, and the cup being suspended by the friction between the piston head and the inner wall of the cup.

As shown in ld ig. 1 the upper end of the cup is threaded and is litted with a metal cap 9, perforated, as at 10, to admit air into the chamber ll on one side of the piston head, the other side et' the piston head torno ing with the cup a chamber l2 communicating with the pipe 3. The cap 9 of the cup may be guided on the lower end of the pipe in any suitable way, the drawings showing a sutliciently large aperture to freely receive the pipe.

in practice, with a cup two inches across, the pressure would not be so great as to preclude moving the piston and cup, relatively to each other, by hand, but, of course, a complete vacuum is not created. ltlowever, any suitable means may be employed for forcing the cup downwardly with respect to the piston head, which will tend to create a vacuum in the chamber l2, and in order to make this chamber 12 the more air tight a small quantity of water or other sealing liquid may be poured in the chamber 11, which will lie above the piston head and act somewhat like a hermetic seal.

In Fig. l of the drawings the means for forcing the cup 7 downwardly is shown as comprising a threaded sleeve le provided with a base flange l5 engaging the cover of the cup and cooperating with the vertical portion of the pipe threaded as at 16. In Fig. 2 the arrangement is substantially reverse, that is the cup is held stationary while the piston is operated, and this may be done in several ways. In the drawings la designates the tree, 2a the bore, 3a the conduit pipe, which may be threaded as at 4a, and this conduit pipe instead of being formed integral with the cup may be connected to it as shown by a screw-threaded joint.

In this construction a slightly modified packing for the piston head is shown, 5 designating a metallic disk having the leather or rubber friction disk 6 on both sides of same to engage the interior wall of the cup 7a. The top of the cup in this view is shown as tapering, as at 8a, and provided with a threaded nipple to receive the end of the pipe 3a.

The lower end of the cup is provided with a removable threaded cap 9a provided with air openings and having a threaded boss l0a to receive a threaded rod 13a, the upper end of which may be connected with the piston head in any suitable way to swivel thereon, shown conventionally at 14a, and the lower end of the rod being provided with an operating handle l5a which may pass laterally through a bore 16a, for convenience in turning the rod. In this construction the air is admitted to the chamber lla on the lower side of the piston, the vacuum being created in the chamber 12a on the upper side of the piston.

In operation, and referring to Fig. l, it will be observed that upon turning the nut 14 (which may be done rapidly in a ratchetlike fashion by applying a pipe wrench thereto) the cup will have great leverage exerted on it to force the same downwardly, creating a vacuum in thechamber 12 for sucking the sap or turpentine through the pipe 3.

In Fig. 2 the cup remains stationary while the threaded rod 13a is turned by the handle 15a, drawing the piston head downwardly and forming a vacuum in the chamber 12a, the liquid, sap, or turpentine above the piston tending to seal any leakage therearound after a hermetic fashion.

Having thus described practical and preferred embodiments of the invention, the particular features of novelty will now be pointed out more succinctly in the following claimszl. The combination of a cup, a piston head snugly fitting therein and forming an air tight chamber on one side thereof, the chamber on the opposite side of said piston being open to the atmosphere, and a pipe suspending said cup and communicating with said air tight chamber at one end and at its other end bent at an angle and adapted to be inserted and securely fitted within an angular bore formed in a tree, and said cup and piston being movable relatively to each other for creating a vacuum in said air tight chamber and causing a substantially continuous suction in said inserted pipe, sub# stantially as described.

2. 'Ihe combination of a cup, a snugly iitting piston therein adapted to form an air tight chamber at one end of said cup, the other end of said cup being open-ended, a pipe leading into said a ir tight chamber and at it-s other end adapted to be inserted and securely fixed within a bore formed in a tree, and a cap provided with perforations for closing the open end of said cup, and said cup and piston being movable relatively to each other for creating a vacuum in said air tight chamber and causing a substantially continuous suction in said inserted pipe, substantially as described.

In testimony whereof, I afiX my signature, in presence of two witnesses.
